Synonymer:
BCIG, X-GAL, (2S,3R,4S,5R,6R)-2-((5-Bromo-4-chloro-1H-indol-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol
Thermo Scientific X-Gal (5-bromo-4-chloro-3-indolyl-beta-D-galacto-pyranoside) is an inert chromogenic substrate for beta-galactosidase which hydrolyzes X-Gal into colorless galactose and 4-chloro-3-brom-indigo, forming an intense blue precipitate
Induction of the lacZ gene with IPTG leads to the hydrolysis of X-Gal and to the development of blue colonies.
